Rigid Frame Steel Building - Tapered Member Frame

This tapered member frame is typically used in clearspan situations from 40 ft. to 150 ft. It can be either gable or single slope. Common roof slopes of ¼ to 4 in 12 are offered. When large clearspan areas are required for special industrial and commercial projects, the clearspan frame is typically the economical choice. The clearspan can be used with either cold-form purlins or open web joists.

Rigid Frame Steel Building - Solid Web Rigid Frame
The solid web rigid frame with interior columns provides multiple spans on wider buildings. It can be either gable or single slope. This frame type is economical with individual spans of 40 feet to 80 feet and building widths from 80 feet to 300 feet plus. Roof Slopes are ¼ to 1 in 12.

Rigid Frame Steel Building - Straight Column Rigid Frame
The straight column rigid frame is ideal for maximum efficiency of interior space. It is suitable for all types of small buildings that require clearspans from 20 feet to 60 feet. Roof slopes of ¼ to 1 in 12 are available. The Tapered Beam frame is ideal for partitioning interior bays and small crane support systems.

Standard Rigid Frame Steel Building Features

Primary Framing

Solid I-Beam Construction for Optimum Strength of Your Building

Our design uses the highest yield strength material, allowing for a smaller web which not only provides a space-saving design, but a greater cost savings to our customers. Laser cut, pre-punched and sub-arc welded to ensure the highest precision.

End Wall Frames and Columns

Your end wall frames and columns are based on your specific building design requirements using either cold formed, mill-rolled or built up I sections to ensure it provides the greatest functionality.

Secondary Framing


8” or 10” based on design requirements. Cold rolled Z-section, 13 gauge to 16 gauge ASTM A- 570, 50,000 or 65,000 psi yield material used to provide maximum strength. By-Pass girt system over laps at sidewall columns forming a continuous connection for extra strength.


8”, 10”, 12” based on design requirements. Top mounted to your roof girders with a varied lap of 2’ to 6’ for strength and cost savings in the erection labor. Maximum purlin spacing is 5’ on center. Purlins also use the By-Pass system for maximum strength

Eave Strut

Cold formed C-Section that is rolled for the appropriate roof pitch to help insure all Worldwide buildings are weather tight at the eave.

Sheeting Angle

A continuous angle supplied with every Worldwide building for the attachment of the sheeting at the rake of the building for ease installation of your sheeting and ensuring a weather tight seal along the gabled eave.

Base Angle/Girt with Trim

A continuous angle or girt supplied with every Worldwide building for the attachment of your sheeting to the concrete. This is easily attached with ram-sets or equivalent anchors by others. Ensures a weather tight seal along the base of your Worldwide building.


Every Worldwide building comes supplied with bracing in your walls and roof to prevent longitudinal loads and truss racking. This is accomplished by diagonal rod, cable, wind columns or portal frames based on your design needs.

Angle Flange Bracing

Provided with every Worldwide building to connect your rigid frames to the Purlins and Girts. This ensures that allowable compression levels are adequate for any combination of loadings.

Purlin bridging angles may be provided at each mid-bay to assure consistent purlin spacing and stiffening.

Structural Bolts

Structural bolts used with Worldwide buildings meet requirements of ASTM standards. ASTM Standards require A-325 for primary frame connections and A-307 for secondary framing.

Self Drilling and Self Tapping Fasteners

Pre-assembled with neoprene washers and domed metal caps to help ensure weather tightness of your steel building. This prevents leakage and prevents potential water damage. One of many features that sets a steel building apart from traditional construction.


80,000 psi

80,000 psi yield material is the standard on all Worldwide Steel buildings. Some manufacturers use a lower yield strength material, which is less resistant to damage from hail and other impacts.

All Coil Steel

All coil steel with Galvalume coating standard (1.25 oz – hot dipped) on each side helps prevent deterioration of the steel sheeting.

Deeper High Rib

Deeper High Rib with more frequent corrugation provides superior strength for the steel building.

Purlin Bearing Rib

The purlin bearing rib provides a better weather seal between the roof sheets on your steel building.

Optimal Semi-Concealed Panel

This configuration is available for walls, facade systems, soffit material, etc. to add an aesthetic appeal to your Worldwide Steel building.



For roof side laps, end laps, and flashing gable is provided to help ensure weather tightness. Nominal 3/8” x 1/8” thick pressure sensitive tape sealant for ease of installation.

Pre-formed High Rib Ridge Cap Panel

Matches the slope and profile of the adjoining roof panels on Worldwide buildings to help ensure constant alignment and weather tightness.

Long Overlap

Provided to help prevent water from siphoning into the building.

Plans & Drawings

Anchor Bolt Setting Plan

Demonstrates building reactions for all buildings. Details where your column locations are for an exact location of your anchor bolts.

Engineer Certified Erection Drawings

Including wall and roof framing diagrams, cross sections, sheeting and flashing details are provided. These drawings show clearly the proper erection and assembly of all building components

Worldwide Building Manual

Erection drawings provided step by step instruction for assembly of your building

Part Numbers

Placed on each component (other than bolts and fasteners) These part numbers coincide with a detailed listing contained in the construction drawings and shipping list to help with assembly of the building.
